Rearchitect Your Code Using Test-Driven Development

Dzone - DevOps

"Write your unit tests before your code," an adage that every developer knows by heart, in theory, but seldom practices it in reality. Test-Driven Development (TDD) is a novel concept that instructs developers to write unit test cases before writing even a single line of code.

What Is Test-Driven Development and Why It’s Important

Dzone - DevOps

One of the most essential steps of any software development project is testing. But when should software undergo testing? It seems logical to test the project when it is completed. However, the power of the classic test procedure is limited.

I Tried Test-Driven Development for A Month and Survived

Dzone - DevOps

When I first heard about Test Driven Development (TDD) I immediately wrote it off as a technique that will slow me down, how on earth should I know exactly what my code will look like if I often refactor while coding. Then I realised TDD doesn’t mean what I thought it meant, you see the first time TDD was explained to me many years ago I was told “You write all your unit tests first” and that is what stuck with me.

Test-Driven Development is not Merely “Test-First”

Net Objectives

Test-first yields analysis, it helps us determine what is clear, what is unclear or missing, and ferrets out misunderstandings. Unit tests are unforgiving, they don’t let you get away with anything. But Test-Driven Development also creates better design. Bad design is hard to test, and so moving tests into a primary position reveals the pain … Continue reading "Test-Driven Development is not Merely “Test-First”".

Test-Driven Development and the Cycle of Observation

Code Simplicity

Today there was an interesting discussion between Kent Beck , Martin Fowler , and David Heinemeier Hansson on the nature and use of Test-Driven Development (TDD), where one writes tests first and then writes code. ” Kent often (though not always) liked writing tests first so that he could observe their behavior while coding. It’s possible to minimize this point and say it’s only relevant to debugging or testing. Write a test (action).
